Abstract

A process for the decomposition of an alkyl tert-alkyl ether to produce the corresponding olefin and alcohol, is characterised in that the alkyl tert-alkyl ether is fed to a distillation column containing a catalyst suitable for the decomposition of the ether, the olefin produced being continuously withdrawn from the top of the column, and the bottom product consisting of pure alcohol or at least a mixture of alcohol and ether.
